Question

A rectangular prism has length thirteen meters, width six meters, and volume three hundred ninety cubic meters. What is the height of the prism?

A. four meters

B. five meters

C. nineteen meters

D. seventy-eight meters

Answer 1

volume of a rectangular prism = length x width x height
length = 13m
widht = 6m
height = h

volume = 390

so \(\begin{matrix}
volume &=& length& \times &width& \times &height\\
390&=&13& \times & 6 & \times & h
\end{matrix}\)

solve for "h"
